The aim of the project is to allow users to create images out of PDF files. It is based on the java.net pdf-renderer library accessible at https://pdf-renderer.dev.java.net/.
This project is licensed under the LGPL, as is the pdf-renderer project.
I have finally managed to cobble a pom.xml that creates a signed jar and a jnlp file. You can launch an instance of the app from my website. It is self signed, so there will be a warning about running untrusted code.
